Question

A diathermic wall permits the flow of heat . If true enter $1$ , else enter $0$

Answer 1

HintFirstly we have to figure out what type of system is a closed system, because of the existence of a closed system the importance of a diathermic wall exists. Then we can observe that the flow of matter across the surface of the wall is not permitted, but the transfer of the energy is feasible, thus yes would be answered.

 Complete step-by-step solution:
Firstly we have to sort out what we have got :
The type of the wall is : Diathermic
In the field of thermodynamics, a diathermal wall is a specific kind of separation between two thermodynamic systems to observe the behaviour of interaction of systems. It is a separation between two thermodynamic systems that allows heat transfer but does not allow transfer of matter across it.
The diathermal wall is really important for thermodynamic processes because, in thermodynamics, it is customary to assume a priority, for a closed system( where the amount of matter across the system remains constant and no ultimate change of matter occurs ). Here the physical existence of transfer of energy across a wall that is impermeable to matter but is not adiabatic.
Thus the transfer which is called transfer of energy as heat, though it is not customary to label this assumption separately as an axiom or numbered law.
Hence, the ultimate answer is yes so ans is true = $1$ .

Note:- It is in the basic definition of the diathermal wall that the transfer of energy takes place. Hence heat is permitted due to being a type of energy, more of a transferable energy. It is also important that the wall should be diabatic for the closed scenario, otherwise the matter will definitely change.
